uncorrectable “error" on form 2210 line D

Turbo Tax calculated an underpayment penalty despite a healthy refund. It also asked for us to fix "Form 2210: Line D Withholding. The sum of the four columns is not equal to your total withholding. . . "

 

The window to the form 2210 only shows 3 possible places to make a  correction entry  with two columns in the form 2210 sharing one of them. The widow does not allow not allow me to make corrections. It also indicates a very large amount in one of the columns which is a large multiple of the amount we actually had withheld entered during the income part of the tax program.
